SPEGIEECATION forming part of Letters Patent No. 616,147, dated December 20, 1899.

Application filed March 16, 1898. Serial No. 674,122. (No model.)

' and State of Michigan, have invented certain new and useful Improvements in Acetylene- Gas Machines, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention consists in the peculiar arrangement and combination of parts, as more fully hereinafter described and claimed.

In the drawings, 'Figo-re lisa perspective vieivoi my apparatus. Fig. 2 is an elevation of the gasoineter, showing the controlling mechanism for the water-supply pipe leading through the top of the generator and its conneetions.

A is a gesonceter comprising the water-tank and passing into the gasometer, arranged to o and gas-tank Z2, of ordinary construction.

B is the gas-inlet pipe, whichenters the tenir a near the hottointhereof and inside of seid tank is formed ini-o a coil c, .terminating in an upwardly-extending pipe d, which rises above the waler-level in the tank. C. is the ges-ou tiet pipe, which also passes through the teni: c near the bottom .thereof and is providedwith the upward extension le, rising beside the pipe (L B is a pipe connecting with the tenir a., preferably near its upper end, but et a point below the lowest water-level therein. This pipe preferably extends downward-and then up-` ward again, terminating in a laterallyextending section f. The' pipe T5 outside of the tank a comprises the upward extension g', which rises to a point above the pipe f, the laterallyextending section h, and the vertical'section i, the latter connecting with the pipe f.

E is the generator, preferably in the iornrl of a cylindrical casing havinirJ a lill-apertureA et its upper end .and the detachable cover F therefor, the latter being secured so as to forni e geetight joint either by haring a screwtlireaded engagernent with e flange on the easing E or by sealing with cement or in any other suitahie way. Secured into the cover lil' is the pipe j, which forms both an outlet for the gas and an inletfor the water. This pipe is detachably connected with the pipef by e Fig. 3 is a vertical section` coupling or union G, preferably the ordinary form of pipe-union.

1I is a valve located in the upwardly-extending portion ofthe pipe D.

. I is a controlling-lever, at one end of which is the weight J and at the other end the loop Zz. K is a chain connected tothe upper tank b of the gasometer and passing down through the loop k of the lever l. L is a weight at the lower end of this chain, and l is a pin or stop in the chain above the loop 7c, adapted to engage therewith when the tank l) is lowered. l

Mis a bracketsecuredto the tank, n which the weighted end of the lei/eri normally rests. N is a valve in the pipe i, preferably a three-Way valve, and O is an escape-pipe with which the third passage of said vali/'eis adaptv have its' end normally sealed by the water therein, but tobe uncovered when the tank brises above .a certain point.

AQ is a fill-spout on the side of the tanica. The' parts being .constructed and arranged as shown and described, the operation is as follows: rlhe tank a ofjthe gasoineter is filled,

through the spout Qfwith water up to the proper level. In the receptacle E ie placed a quantity of carbid of calcium, and after the cover 'F is secured in place the receptacle is connected with the pipe j by means of the cOupIiDgG. When the gas-tank b is in: its lowered position, the stoppt will engage with the loop 7o of the lever I, and the Weight L on the lend of the chain will draw the lever l down intoa position Where the valve H is opened. 'lhiswillallowthe water to pese through the pipe D into the section j" thereof and through the section j into the receptacle E, where it will fell ony a perforated distributing-plate Rend, coming into contact with the carbid, it will cause the generetcn of the gas, which will pass up through the pipes j andfinto the section z' of the pipe B and through the section 7l, thecoil c, and riser ol into the gas-tenir Z2. In passing through the in the gas-tank. When 'the tank i) rises sutciently to drew the stop Zout ci engagement coil c the gas will be cooled before liberation.'

with the loop It, the weigiitJ on the opposite end of 'said lever Will cnnse the Valve H-to l.-close, thns cutting off the water-supply to' the generator, stopping the generation of ges. Should the tank l) rise to aheight where there .is danger of breaking the water'seal, the end ofthe pipe l? will be" uncovered and allow somo of the gas to escape into the pipe 0. When. the chargent' .carbid is exhausted, the receptacle E may be readily detached by un-d fastoning the coupling O, after which the re#4 ceptncle may loe emptied and refilled. Before disconnecting the receptacle, however, the valve N is turnedy into :t position where it will shut oii communication with the pipe -z and open connection with the cscape-pipe 0. This willallow the gas which remains in the receptacle E to escape before said receptnole isdetochcd, and thus prevents its escaping into the room. At the seine time the gus in the gnsometer is held from escaping while the generator-receptacle is detached. After the receptacle-is refilled and replacedthe valve N may be left in the same position long enough to allow the generation of gas to start, and thus the air containedin the receptacle will be forced out through the ventpipe O. The Valve may then be turned-to shut off seid vent-pipe and open connection 30 with the pipe B. By this errangenient all danger of forming an explosive mixture of gas and air is avoided.

'What I claim as my invention isl. In sigas apparatus, the combination with ageneretor, and a getsometer, of awater-supply pipe for said generator connected therewith, a gas-inlet pipe for the gasomete'r connecting with said water-supply pipe, a gasescftpe pipe connecting with said ges-inlet pipe, and a valve controlling said gas inlet and escape pipes, and adapted to establish or clit 01T communication between the ,ges inlet or escape pipes and the watcr-supplypipe.

2. In e gas apparatus, the combination with e gasometer provided with a Watertankfand it ges-generator, of a water-supply pipef con nec'ting the Watentank and 'generator and provided with a lateral extension, a. gas-inlet pipe for the gasorneter having a connecting portion extending upwardly from sid Watersnpply pipe, eges-escape pipe oo n neoting with seid. upwardly extending connecting portion, a three-Way Valve controlirig said gse inlet and escape pipes nndadapted to es tablish or eut off communication between the saine and the Water-supply. pipe, and a controlling-valve for said netter-sapplyl pipe.

3. Ine ges apparatus,the combination with the generator-casing `'and a gdsompeter provided with gasinlet and Water-outlet pipes, of n littoral extension of scid water-pipe leading to and connected with said generator, a connecting-pipe extending 'upward from said lateral pipe to said gas-inlet pipe, a valve in said npwardlyextending pipe below its connection with the gas-inlet pipe, a controlling-valve in said Water-pi pe and a coupling in said laterally-extending pipe between seid upwardly-extending connectingfpipe and the generetor. i

. Il. The combination with the gcneratoncasing, e gesometer provided with gas-inlet and water-outlet pipes and a common pipoconnecting said ges and 4v vaterpipes with lthe generator-casing, of a coupling insaid conimon pipe, avalve controlling sztid'Water-pipe, a three-way valve controlling said ges-inlet pipe,and an escape-pipe with which said valve is edapted to connect said generator when turned to cut'oi said gasometer. In testimony whereof I affix my signature in presence of two witnesses.
